assuming, therefore, that the 12 Caban 5 Kayab in AlSb-Bl8a had 

 the same Initial-series value as the 12 Caban 6 Kayab in plate 19, A, 

 B5-A6, namely, 9.14.13.4.17. Reducing the number in Bl7-Al8a, 

 namely, 1.16.13.3, to units of the first order, we have: 



13, 223 



Remembering that this number is to be counted forward from the 

 date 12 Caban 5 Kayab, and applymg rules 1, 2, and 3 (pp. 139, 140, 

 and 141, respectively), the terminal date reached will be 1 Ahau 3 

 Zip, which is recorded in Al9. Compare the coefficient of the day 

 sign in Al9a with the coefficient of the katun sign in AlSa, and the 

 day sign itself with the profile variant for Ahau in figure 16, 7i', i'. 

 For the month sign, compare Al9b with figure 19, d. But since the 

 Initial-series value of the starting point is known, we may calculate 

 from it the Initial-series value of the new terminal date: 



9.14.13. 4.17 12 Caban 5 Kayab 



1.16.13. 3 

 9.16.10. 0. 1 Ahau 3 Zip 



Passing over to the east side of this monument, the student will find 

 recorded there the continuation of this inscription (see pi. 20).^ This 

 side, like the other, opens with an introducing glyph A1-B2, which 

 is followed by an Initial Series in A3-A5. Although this number is 

 expressed by head variants, the forms are all familiar, and the student 

 %vill have little difficulty in reading it as 9.16.10.0.0. The terminal 

 date wliich this number reaches is recorded in B5-B8; that is, 1^ Ahau 

 3 Zip, the "month indicator" appearing as a head variant in A8 with 

 the head-variant coefficient 10. But this date is identical with the 

 date determined by calculation and actuall}' recorded at the close of 

 the inscription on the other side of this monument, and since no later 

 date is recorded elsewhere in this text, we may conclude that 

 9.16.10.0.0 1 Ahau 3 Zip represents the contemporaneous time of 

 Stela F, and hence that it was a regular hotun-marker. Here again, 

 as in the case of Stela J at Quirigua, the importance of the "contem- 

 poraneous date" is emphasized not only by the fact that all the other 

 dates lead up to it, but also by the fact that it is expressed as an 

 Initial Series.

2 The frontlet seems to be composed of but one element, indicating for this head the value 8 instead 

 of 1. However, as the calculations point to 1, it is probable there was originally another element to the 

 frontlet
